Preliminary analysis of the effect of controlling mining subsidence with waste stow for long wall workface
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 11
Abstract
Based on the brief introduction of the long wall workface mining principle stowing with waste dump, the long wall face waste stowing mechanism and process of mining subsidence are analyzed in this paper. The conceptions about effective stowing thickness and equivalent stowing height are also proposed, and the forecasting models for cover rock destruction and surface subsidence of waste stowing mining of long wall workface are established in this paper. With combination of the geological mining condition of 3# coal mining area in Yanzhou coal mine, the specific effect of controlling mining subsidence with waste stowing is analyzed in the paper.
